In April Hemsworth, 28, was seen rubbing his wife’s baby bump on the red carpet at the European premiere of The Avengers.

Following the announcement of her pregnancy, Pataky said: “Having the person that you love by your side, and starting a family with them is the best thing that can happen to you in this life.”

Now her husband, who plays Thor in The Avengers, is going to have to be a real-life superhero. He has to be on diaper duty while promoting his two other films that open this year – Snow White and the Huntsman and Red Dawn.
